Description

foot drop orthotics

technical field

The invention relates to the technical field of medical devices, in particular to an orthosis for preventing and treating foot drop.

Background technique

At present, the method commonly used in clinical practice to prevent and correct foot drop is to use orthotics. Orthotics are usually composed of high-density sponge lining pads inside the brace, and the rest is at a 90-degree angle. 90° neutral fixation. It is suitable for patients who are bedridden for a long time to prevent foot drop, patients with Achilles fasciitis, patients with gastrocnemius spasm, patients with acute ankle sprains and patients recovering after fractures. The brace of the orthosis can play the role of plaster fixation, which can not only avoid skin and muscle problems caused by plaster fixation, but also maintain the functional position of the limbs, speed up recovery, and have strong air permeability. However, generally the foot drop orthosis on the market has a single function and only serves to fix the functional position. During the period of wearing the orthosis, the patient cannot massage and exercise the muscles of the limbs, especially the gastrocnemius muscle. In this way, for the affected side Limbs with poor circulation in the lower extremities are prone to the formation of venous thrombosis in the lower extremities.

At present, most of the instruments used clinically to prevent venous thrombosis of lower extremities use arteriovenous air pressure therapy instrument, which can promote venous return, prevent blood stasis, reduce edema of hemiplegic limbs, and prevent venous thrombosis of lower extremities. It is effective in preventing venous thrombosis of the lower extremities and edema of hemiplegic limbs; however, the instrument is bulky and the operation steps are relatively cumbersome, requiring medical staff to operate it.

Contents of the invention

The technical problem to be solved by the present invention is to provide a foot drop orthosis, which can solve the problem that the existing foot drop orthosis has a single function, but only plays a role of fixing the functional position and cannot massage the gastrocnemius muscle, resulting in poor circulation of the lower limbs on the affected side. And prone to the formation of lower extremity venous thrombosis.

In order to solve the above problems, the technical solution of the present invention is: this foot drop orthosis includes a brace and an air pressure therapy instrument, and the air pressure therapy instrument includes an air pressure treatment box and an air bag, and the box body of the air pressure treatment box includes a voltage Display table, pressure indicating table, treatment time knob, inflation and deflation time knob, an air pressure pump is set in the box, the air pressure pump is connected to the power supply and controlled by the time controller and the air release valve; The air bag arranged outside the box is connected through the air pipe.

Among the above technical solutions, a more specific solution can also be: the bottom surface of the brace is provided with a connection base; the brace is fixedly connected to the air pressure therapy box through the connection base; the airbag is fixed by a strap when in use On the brace, it acts on the gastrocnemius muscle of the lower limb of the affected side of the patient.

further: the

Owing to adopting above-mentioned technical scheme, the present invention has following beneficial effect:

1. Add two sets of airbags with ventilation channels in the orthotic brace, and connect the air pressure therapy box adjustment table to the brace base. There are visual voltage screen, inflatable pressure pump, power supply path, components for controlling time, etc. in the box. When the power switch is connected, the two sets of air bags in the brace are inflated and deflated according to the adjusted pressure through the action of the air pump. Inflation, deflation and treatment time are made with different knobs for adjustment. In this way, the gas is repeatedly inflated and deflated sequentially, which promotes the blood circulation in the affected part, effectively prevents the phenomenon of blood retention, prevents the formation of thrombosis in the lower extremities, and promotes the disappearance of edema in the extremities.

2. The power supply of the entire air pressure matching device of the present invention is a 12-volt storage battery, which is safe and reliable, and can be repeatedly charged in time according to the voltage situation of the display screen. Power can maintain continuous treatment time up to 3 days. The orthosis of the invention is small in size and easy to operate. The air pressure and inflation and deflation time settings can be set as default values. It is safe and practical. It is cheaper than clinically applied arteriovenous air pressure therapy instruments, and each only costs about 1,000 yuan. , can be extended to family use.

3. The orthosis of the present invention is small in size, and the box can be disassembled according to the needs of treatment. The operation is simple and does not depend on medical personnel to operate. It is especially suitable for preventing the occurrence of lower extremity venous thrombosis in patients with risk of foot drop.

detailed description

Below in conjunction with accompanying drawing and embodiment the present invention is further described:

The foot drop orthosis of Fig. 1, Fig. 2 and Fig. 3 includes a brace 1 and an air pressure therapy instrument, and the brace 1 is provided with a high-density sponge inner lining pad; the air pressure therapy instrument includes an air pressure treatment box 3 and two groups The air bag 5 and the air pressure treatment box 3 are provided with a voltage display gauge, a pressure indicator gauge, a treatment time knob, a filling and deflation time knob and a power charging interface, and an inflatable pressure pump is arranged in the box. The time controller and the air release valve control the power on and off; the inflation pressure pump is connected to the air bag 5 arranged outside the box through the air pipe 4 . The bottom surface of the brace is provided with a connection base; the brace 1 is fixedly connected with the air pressure treatment box 3 through the connection base 2, and can be removed at will according to the treatment situation; when the airbag 5 is in use, it is fixed on the brace by a strap 6, acting on The gastrocnemius muscle of the patient's lower extremity. The air pressure treatment box of the present invention uses a 12-volt battery as a power source, and has a rechargeable alternating current mode at the same time; the time controller in the box controls the power on and off of the electromagnetic air pump and the air release valve; when the electromagnetic air pump and the air release valve are powered simultaneously, the air pump supplies gas, the vent valve is closed. The pressure in the airbag 5 is controlled by a pressure regulator, and the pressure is adjusted through the pressure adjustment knob according to the patient's condition, and the pressure situation can be understood through the pressure indicator gauge. The airbag inflation time can be controlled according to the inflation time adjustment knob. When the inflation time is reached, the instrument will be powered off at the same time, the air pump will stop supplying air, and the air release valve will release the gas in the airbag. The time of deflation can also be set by Adjust the deflation time adjustment knob. Inflate and deflate repeatedly in this way, so as to achieve the effect of promoting blood circulation in the treatment area, treating limb edema, and preventing the formation of venous thrombosis in the lower limbs.

In the present invention, the brace of the foot drop orthosis plays the role of correction and fixation; the air pressure treatment box is small in size and easy to operate, and can be hung on the base of the brace when treatment is needed, and can be disassembled at will; Cloth-wrapped bandages are placed on the active parts respectively, and connected with the air pressure therapy box through the connecting tube; the air pressure therapy box transmits the air pressure for treatment through the air connection hole. When in use, turn on the switch, the working indicator light is on, and start to work; at the same time, it can be charged in time according to the situation of the voltage display meter; at the same time, the pressure can be adjusted or set through the pressure adjustment knob according to the patient's condition; and then according to the patient's condition, through inflation The time knob and the deflation time knob set the cycle time of inflation and deflation; the treatment time of the entire cycle is controlled by the treatment time knob until the treatment time is over, and then it stops working.
